Paul-Michel Foucault (UK: /ˈfuːkoʊ/, US: /fuːˈkoʊ/; French: [pɔl miʃɛl fuko]; 15 October 1926 – 25 June 1984) was a French philosopher, historian of ideas, writer, political activist, and literary critic. Foucault's theories primarily address the relationship between power and knowledge, and how they are used as a form of social control through societal institutions. Though often cited as a structuralist and postmodernist, Foucault rejected these labels. His thought has influenced academics, especially those working in communication studies, anthropology, psychology, sociology, criminology, cultural studies, literary theory, feminism, Marxism and critical theory.
